Claims.

This invention relates to weaving looms.

It is an object of the present invention to provide a weaving loom which may be readily and easily adjusted for weaving pads of various sizes.

' It is another object of the present invention to provide a weaving loom including a pair of cross pieces adapted to be disposed at right angles to each other within the loom, thereby dividing the loom transversely as well as longitudinally as desired.

Other objects of the present invention are to provide a weaving loom bearing the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is easy to use and efficient in operation.

For other objects and for a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a perspective view of a weaving loom embodying the features of the present invention;

Fig. 2 is an enlarged, fragmentary perspective view of one of the cross pieces;

Fig. 3 is a vertical sectional view taken alon line 3--3 of Fig. 2;

Fig. 4 is a view similar to Fig. 2 but showin another of the cross pieces;

Fig. 5 is a vertical sectional view taken along line 55 of Fig. 4 and I Fig. 6 is a vertical sectional view taken along line 68 of Fig. 1.

Referring more in detail to the drawing, in which similar reference numerals identify corresponding parts throughout the several views, there is shown an adjustable weaving loom, referred to collectively as l0, and including a rectangular, preferably square-shaped, frame ll having four side bars l2, I3, [4 and I5, substantially as illustrated. The side bars are integral with each other and are preferably in the form of metal stampings. Since the frame will be formed of relatively light gauge stock, it is preferable to reinforce the side bars l2-I5 with lateral, inwardly extending flanges l6 integrally formed in the lower longitudinal edges thereof, these flanges being connected at their ends by integral triangular portions ll, each of which mounts a rubber cushion [8, as shown in Fig. 1.

Each of the frame bars is provided with upwardly extending teeth [9 integrally formed in the bars and adapted to cooperate with each other to hold the warp and woof threads during weaving, as is well known in the art.

A cross piece 20 is provided consisting of an 2 elongated strip 2| integrally formed at each end thereof with a flange 22 extending at right angles thereto. Each flange 22 is provided with a pair of vertically spaced slits defining an outwardly bent loop 23 integrally formed therein.

The strip 2| is of just the right length to permit the flanges 22 to slide in between oppositely disposed teeth, as shown in Fig. 1, with these teeth sliding into the loops 23 at each end whereby to releasably secure the cross piece in the desired position defining a smaller weaving area inter-.

mediate the side bars I4, I5 and I6.

For greater strength, the bottom of strip 2| is provided with an elongated bead 24, while the top of the strip is provided with upwardly extending teeth 25 integrally formed therein and adapted to cooperate with each other in the same manner as the teeth I!) to hold the warp and woof threads during weaving.

Downwardly extending slots 26 are provided intermediate each pair of teeth 25 in the strip 2|, extending to the head 24 for a purpose which will hereinafter become clear.

A second cross piece 21 is provided consisting of an elongated strip 28 integrally formed at each end thereof with a flange 29 extending at right angles thereto. Each flange 29 is provided with a pair of vertically spaced slits defining an outwardly bent loop 30 integrally formed therein.

The strip 28 is of just the right length to permit the flanges 29 to slide in between oppositely disposed teeth l9, as shown in Fig. 1, with these teeth sliding into the loops 30 at each end whereby to releasably secure the cross piece 21 in a manner to be hereinafter described.

For greater strength, the middle portion of strip 28 is provided with an elongated bead 3|, while the top of the strip is provided with upwardly extending teeth 32 integrally formed therein and adapted to cooperate with each other in the same manner as the teeth l9 and 25 to hold the warp and woof threads during weaving.

Downwardly extending slots 33 are provided intermediate and below each pair of teeth 32 in the strip 28, extending from the bottom of bead 3| to the bottom edge of strip 28.

As shown in Figs. 3 and 5, when the cross piece 21 is inserted intermediate oppositely disposed teeth IS in the frame II and at right angles to the cross piece 20, with the teeth I9 entering loops 30, the bead 3| thereof is received in slot 26 of cross piece 20, while the bead 24 of cross piece 20 is received in slot 33 of cross piece 21.

Thus there is defined a further restricted weaving area intermediate the cross pieces 20 and 21 and side walls I 4 and I5, as shown in Fig. 1.

It will be obvious that any weaving area dein connection with looms of this character and a will not be described in detail, the present invention residing in the construction of th'el'oom' permitting it to be readily adjusted to mats of different sizes both longitudinally and laterally.

While various changes maybe made'in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the invention as defined in the, appended.

claims.

Having thus set for-thand disclosed-the nature of 'ou r invention, what is claimed is:

1. An adjustable weaving loom comprising. a rectangular frame having four side bars, :each of said bars having upwardly extending. :teeth adapted to cooperate with each other to receive 1 the warp and woof threads during weaving, a first cross piece having upwardly extending. teeth adapted to cooperate with said side bar teeth and adapted to fit in between oppositely disposed side bars, means for releasably securing said first cross piece said position, and asecond' cross piece having upwardly extending teeth adapted to cooperate with saidsidebar teeth and adapted to lit in between *oppositely, disposedside i'bars,

second means for releasably securing said second J cross piece in said position, said first and second cross pieces being adapted to mesh with each other atsubstantially :rightangles.

'2. adjustable weaving loom accordingto claim 1, said means for releasably securing said first and second cross pieces to said frame com prising integrally formed flanges at the ends of said pieces, said flanges being bent at substantially right angles to said pieces and having a pair of vertically spaced slits defining an outwardly bent l'oopintegrally formed therein, said loop in each of said flanges being adapted to receive one of said side bar teeth.

An adjustable weaving loom according to claim 2., said first cross piece intermediate said teeth therein having downwardly extending slots, saidysecondfcross piece intermediate said teeth therein and extending upwardly from the bottom edge. thereof havingsecond slots adapted to coopcrate with said slots in said first cross piece when said pielee's mesh.

4. An adjustable weaying loom according to claim 3, saidfirst cross piece below said downwardly extending slots therein having an elongated beadextending longitudinally thereof, said bead being; adapted to fit into saidslots in said second cross piece, said second cross piece intermediate saidteeththerein and said slots extending upwardly from the bottom-longitudinal edge thereof having an elongated bead extending longitudinal-ly thereof, said bead being adapted to fit into said slots in said first piece.

5. An adjustable weaving loom according to claim 4, said four' side bars being integrally connected and each providedat its bottom longitudinal edge Witha lateral ilangepsubstantially triangular portions integrally connecting th e ends of said flanges with each other, and rubber cushe ions mounted in eachof said triangular portions.
